A mixture of 10.6 g (0.045 mole) of previously distilled octyl 1-chloroethyl carbonate, 4.5 g (0.08 mole) of dry KF and 0.6 g (0.002 mole) of 18-crown-6 ether is stirred and warmed at about 85° C. (oil bath ) under a pressure of about 1.87 kPa. After 12 hrs., all the volatile acetaldehyde has evaporated. The mixture is cooled and distilled under reduced pressure. There is obtained 6.87 g of pure n-octyl fluoroformate (86%). b.p.: 74°-77° C. at 533 Pa (4 mmHg).
